Definitions
- the invention relates to a structural element with a incomplete structure forming a dashboard body. It also relates to a cross member shaped to be introduced into the structural element and fixed thereto, and a dashboard comprising the structural element and the cross member.
- the dashboards are installed transversely in the passenger compartment, in front of the driver and front passenger seats.
- the dashboard body constitutes the framework of the dashboard. It is covered with a lining or skin forming the outer wall of the dashboard.
- This dashboard body in particular provides support for various items of equipment such as the dashboard, driving indicators, various control means, for example air conditioning, radio and navigation equipment.
- a dashboard body is composed of many assembled elements. These are generally parts made of polymer or composite material obtained by molding and then assembled by bolting, screwing, etc. The assembly of a dashboard body is therefore relatively complex and the assembly relatively heavy.
- the invention aims to overcome these drawbacks by proposing a dashboard body made in one piece, in particular by an additive manufacturing process called "three-dimensional printing”, also called “3D printing”.
- the object of the invention relates to a structural element forming a dashboard body of a motor vehicle intended to be installed in a transverse installation position inside a vehicle cabin.
- the structural element has a one-piece lacunar structure resulting from a three-dimensional printing, and the lacunar structure defines:
- first internal passage passing entirely through the structural element and extending transversely when the structural element is in the installation position, the first passage being shaped to receive a cross member in particular bent with a constant radius of curvature and comprising at least two elements fixing intended to be fixed to the cross-member, a second internal passage connecting the first passage to a face of the structural element facing the rear of the vehicle when the structural element is in the installation position, the second internal passage comprising at least one fixing element, preferably at least two fixing elements, intended to fix a steering column fixing support.
- incomplete structure is meant a structure comprising cells, perforations, and / or cavities intended to limit the amount of material.
- the amount of material used can correspond to a minimum amount of material necessary for the mechanical strength of the structure for the intended use. This quantity of material can be determined by calculating the forces which the structure must bear, for example for its own strength under its weight, to withstand a force distributed over the surface, for its attachments to the vehicle body, for the integration of 'related elements (fixing interfaces, integration of the HVAC- “heating, ventilation and air-conditioning” block (heating, ventilation and air conditioning), integration of the elements of the storage volumes, etc.).
- the lacunar structure of the structural element according to the invention is thus in the form of a network of material forming meshes and nodes.
- a network can be formed of parts similar to hollow vessels, semi-solid (internal structure also called latice) or solid interconnected.
- the fastening elements of the structural element for fixing the cross-member can be positioned so as to be fixed to an upper or lower zone of the cross-member, in the installation position of the structural element. Attachment to a lower area of the cross member may, however, improve the retention of the cross member.
- the second passage receives the steering column fixing support, on which the vehicle steering wheel will be mounted. It is therefore located opposite the conductor, in the installation position of the structural element.
- the second passage can be connected to the first passage near one end of the first passage and the fastening elements of the first passage are then located between the second passage and the other end of the first passage. This can facilitate the introduction of the cross member inside the first passage.
- the structural element may comprise an internal framework of lacunar structure in one piece with an external skin delimiting at least partially a volume of the structural element, said external skin having an external surface chosen from a lacunar surface, a solid surface , a surface having one or more incomplete and full areas.
- this outer skin can correspond to a visible part of the interior of the passenger compartment when the structural element is in the installation position.
- the second passage then opens onto a face of the structural element provided with this external skin.
- the structural element according to the invention is preferably obtained by three-dimensional printing, for example by depositing molten filament (“Fused Deposition Modeling” - Realization of a model by molten deposit or “Fused Filament Manufacturing” - manufacturing by molten filament) or by selective laser sintering ("selective laser sintering").
- molten filament Fused Deposition Modeling” - Realization of a model by molten deposit or “Fused Filament Manufacturing” - manufacturing by molten filament
- selective laser sintering selective laser sintering
- the material can be a polymer material chosen from acrylonitrile-butadiene-styrene (ABS), polypropylene (PP), polylactic acid (PLA).
- ABS acrylonitrile-butadiene-styrene
- PP polypropylene
- PLA polylactic acid
- the polymeric material can also be loaded with glass or carbon particles.
- the invention also relates to a dashboard cross member capable of being inserted inside a structural element according to the invention.
- the crosspiece comprises a curved tube, preferably hollow, having a constant radius of curvature.
- the cross member can thus be produced in a very simple manner, in particular, the tube can be in one piece and / or can have a constant section over substantially its entire length.
- the section of the tube can be of simple geometric shape, for example circular, although other shapes are possible (oval, oblong, square, rectangular section, etc.).
- the tube can be made of metal, for example steel.
- the crossmember can comprise at least two fixing elements integral with the tube intended for its attachment to the structural element.
- the fastening elements can then extend along the same longitudinal line of the surface of the tube, parallel to a central axis of the tube. This can facilitate the introduction of the cross member inside the first passage of the structural element.
- fastening elements can be U-shaped lugs and secured to the cross member, for example by welding, so that the cross member closes their concavity. They can thus be produced in a simple manner and their attachment is robust.
- this configuration makes it possible to fix (in particular by welding) a nut on the bottom of the U-shaped part, inside of the concavity of the tab, allowing the fixing of a screw passing through an orifice located in the center of the nut.
- the crossbar tube is equipped with a flange at each of its ends, at least one of the flanges being removably assembled to the tube.
- the cross member can thus be introduced inside the structural element via an end without a flange, which makes it easier to introduce it inside the first passage of the structural element but also to reduce the internal dimensions of the first passage.
- This removable attachment can be achieved by a sleeve integral with the flange fitting onto one end of the tube.
- the sleeve can have at least one flat cooperating with a flat at the end of the tube. This allows to precisely position the sleeve, and therefore the flange relative to the tube, which can facilitate mounting of the flange on the vehicle body.
- the presence of a flat also makes it possible to block any rotation of the sleeve relative to the tube when the latter is of circular section.
- the invention also relates to a dashboard of a motor vehicle intended to be mounted inside a vehicle in a transverse direction thereof.
- the dashboard includes:
- a steering column fixing support comprising at least one fixing element to the cross member
- first internal passage passing entirely through the structural element and extending transversely to the vehicle when the dashboard is mounted inside the vehicle, the first passage being shaped to receive the cross member and comprising at least two elements for fixing to the crosses,
- a second internal passage connecting the first passage to a face of the structural element directed towards the rear of the vehicle when the dashboard is mounted inside the vehicle, the second passage comprising at least one fixing element, preferably at least two fixing elements to the steering column fixing support.
- the steering column fixing support is fixed to the structural element inside the second passage
- the cross member is fixed to the element. structural inside the first passage and is fixed to the steering column fixing support.
- the assembly thus obtained has a limited number of parts and fasteners, which makes it possible to lighten its mass and simplify its assembly.
- the structural element and / or the cross-member can be as previously described.
- the crossbar tube can be equipped with a flange at each of its ends, at least one of the flanges being assembled to the tube in a removable manner.
- This assembly can be achieved by a sleeve fitting onto one end of the tube as previously described.
- the structural element can be configured to receive the steering column fixing support under the crossmember when the dashboard is mounted inside the vehicle.
- the steering column fixing support can be located partly in front of the cross member in the installation position of the structural element.
- the steering column fixing support may also comprise a part for receiving the cross member, for example of a shape complementary to the cross member. This can facilitate the introduction of the cross member, the receiving part being able to guide the sliding of the cross member, and also improve the maintenance of the cross member, in particular when the support for fixing the steering column is under the cross member.
- the invention also relates to a motor vehicle comprising a structural body, a dashboard having all or part of the preceding characteristics, the dashboard being fixed to the body via at least four localized fixing zones:
- the invention finally relates to a method for mounting a dashboard according to the invention, comprising:
- the assembly can thus be assembled quickly and easily.
- the steering column fixing support can be fixed under the crossmember, which can help maintain it. It may be partly in front of the cross member with respect to the longitudinal direction of the vehicle.
- the concavity of the crossmember can be directed towards the front of the vehicle when the dashboard is mounted inside of it. This makes it possible to advance the cross member as far as possible towards the rear of the vehicle, in particular at the level of its attachment to the steering column support. Such a close position of the cross member and of the steering column support can make it possible to limit the vibrations which will be transmitted to the steering wheel.
- the cross-member can also extend in a substantially horizontal, or horizontal, plane. Such a position close to the horizontal also makes it possible to reduce the distance between the steering column support and the crosspiece.

- front, rear, upper, lower refer to the front and rear directions of the vehicle, up, down, when the dashboard, comprising the structural element and the cross member, is mounted on the vehicle.
- the X, Y, Z axes correspond respectively to the longitudinal (front to back), transverse and vertical axis of the vehicle.
- substantially horizontal, longitudinal or vertical is meant a direction / plane forming an angle of at most ⁇ 20 °, or even at most 10 ° or at most 5 °, with a horizontal direction / plane, lon gitudinal or vertical.
- substantially parallel, perpendicular or at right angles is meant a direction / angle deviating by at most ⁇ 20 °, or even by at most 10 ° or at most 5 ° from a parallel, perpendicular direction or at a right angle.
- FIG. 1 shows a structural element 10 forming a dashboard body of a motor vehicle.
- This structural element 10 is intended to be installed in a transverse installation position (along the Y axis) inside a vehicle interior.
- this structural element 10 has a lump structure in one piece, here produced by three-dimensional printing (otherwise called “3D printing”).
- a network of interconnected parts similar to vessels 12 can thus be distinguished.
- the thickness and the shape of each of these vessels 12 can be chosen so as to obtain a structure which can be used for the desired use, for example fulfilling the conditions of mechanical strength, stiffness, or the like.
- the interconnection zones of these vessels 12 can be of various shapes and of various dimensions.
- these vessels can be hollow or full. It should also be noted that hollow vessels may include an internal structure forming a network (lattice-shaped or alveolar structure) making it possible to strengthen the structure of the vessel while limiting the amount of material used.
- the gap structure 10 defines:
- first internal passage 14 (see FIGS. 1 and 5) passing entirely through the structural element 10 and extending transversely when the structural element 10 is in the installation position, - A second internal passage 16 connecting the first passage 14 to a face 1 1 b of the structural element 10 directed towards the rear of the vehicle when the structural element 10 is in the installation position.
- the second passage 16 is here connected to the first passage 14 near an end 15a of the first passage 14.
- the position of the second passage 16 corresponds to the position of the driver in the vehicle.
- This second passage 16 is here substantially perpendicular to the first passage 14.

- at least two fixing elements intended for fixing a cross member 20.
- four fixing elements 141, 142, 143, 144 are provided.
- the invention is however not limited by the number of fixing elements. Only two or three fasteners could be provided, or a number of fasteners greater than 4.
- the four fastening elements 141, 142, 143, 144 are arranged between the second passage 16 and the other end 15b of the first passage (see fig.1). As shown in Figure 9, they are for example in the form of an L-shaped tab through which a screw 26a engages with a fastening element 221 of the cross member 20 and a nut 26b. Other types of fastening elements could however be provided, for example collars 32 similar to those used to fix the cross-member 20 to the mounting bracket 30 of the steering column.
- the first passage 14 is further shaped to receive the cross member 20, which is bent with a constant radius of curvature, as described in more detail with reference to FIGS. 6 to 9.
- the second passage 16 comprises at least one fixing element intended to fix a fixing support 30 for a steering column.
- two fastening elements 161 and 162 are provided on either side of the second passage 16.
- it is 2 planar surfaces facing each other, located on each side of the second second passage 16 following the transverse direction Y, each pierced with an orifice for the passage of a screw, a rivet or the like.
- the number of fasteners, or their shape, is not limited.
- the structural element 10 comprises an internal framework 10a of lacunar structure produced in one piece with an external skin 10b partially defining a volume of the structural element 10.
- the outer skin 10b corresponds substantially to the face of the structural element 10 visible from the interior of the passenger compartment when it is mounted inside the vehicle. It thus has an upper face 1 1 a, located under the windshield, and a front face 1 1 b, located opposite the driver and the front passenger, directed towards the rear of the vehicle (see FIG. 2). It will be noted that the second passage 16 leads to the front face 11 b.
- the outer skin 10b itself has a lacunar structure.
- it has an external surface 1 1 comprising gaps and full areas, thus resembling a fabric or network with wide mesh.
- the internal framework 10a comprises vessels 12 on the whole thicker than those constituting the external skin 10b.
- Such an openwork outer skin 10b could possibly be covered with a continuous (solid) technical surface, not shown, such as for example a textile or the like.
- this external skin 10b could have a solid external surface or else a surface having one or more lacunar and solid zones (not shown).
- FIG. 4 represents a dashboard 40 comprising in particular the structural element 10, the cross-member 20 and the mounting support 30 for the steering column.
- the crosspiece 20 is described with reference to Figures 6 to 9. It comprises a curved tube 22 of constant radius of curvature, preferably made in one piece.
- This tube 22 is preferably hollow, which allows a saving of material, advantageously made of a resistant material, such as a metal, for example steel.
- a resistant material such as a metal, for example steel.
- it has a constant circular section over substantially its entire length, namely, over its entire length except for its ends 22a and 22b.
- the tube may have a thickness of 1.5mm and a diameter of 50mm.
- the bending radius may be chosen so as to bring the cross member 20 as close as possible to the final position of the steering wheel, the cross member being mounted in the structural element 10 in a substantially horizontal plane, its concavity directed towards the front of the vehicle.
- a bending radius of around 2500mm can be used.
- the tube 22 can also comprise at least two fixing elements for fixing it to the structural element 10.
- four fixing elements 221, 222, 223, 224 are provided. They preferably extend along the same longitudinal line L at the surface of the tube, parallel to a central axis X of the tube 22, this to facilitate the introduction of the cross-member 20 inside the first passage 14.
- the four fastening elements are identical. They are in the form of U-shaped legs as shown in Figure 9.
- the fastening element 221 comprises two wings 221 a and 221 b connected by a bottom 221c and whose free edges are secured to the tube 22, for example by welding.
- the tube 22 thus closes the concavity of the fixing element 221.
- the bottom 221 c can be fixed to the fixing element 141 of the structural element 10 by means of a screw nut assembly 26a, 26b, the screw 26a passing through the bottom and the fixing element 141, as shown.
- the nut 26b can in particular be fixed to the bottom 221 c, inside the concavity, to facilitate the fixing of the screw.
- the tube 22 is equipped with a flange 23, 24 at each of its ends 22a, 22b. These flanges 23, 24 are intended for fixing the cross member 20 to the vehicle body.
- a cross member is attached to the front legs of the body of a vehicle.
- one of the flanges 23 is assembled to the tube 22 by a sleeve 231 fitting onto the end 22a of the tube.
- This sleeve 231 is provided with two parallel flats 232 and 233 which cooperate respectively with corresponding flats 22c and 22d of the end 22a.
- the tube cannot pivot inside the sleeve, and the flange 23 is positioned correctly relative to the tube.
- the flange 23 is fixed to the tube 22 by a screw-nut assembly 25a, 25b passing through corresponding orifices of the sleeve 231 and of the end 22a.
- the nut 25b can be welded to the sleeve 231, as shown.
- the other flange 24 is permanently fixed to the tube 22, here by welding. It could nevertheless be secured to the tube 22 also by a sleeve.
- the structure of the flange 23 allows its attachment to the tube after the introduction of the tube 22 inside the structural element.
- the flange could be permanently fixed to the tube 22 after introduction of the latter into the structural element, for example by welding or the like.
- the sleeve 231 could be fitted inside the tube 22.
- the dashboard 40 finally comprises a mounting support 30 for the steering column, intended to support the steering wheel.
- This fixing support 30 comprises at least one fixing element 32 to the cross member 20.
- two fixing elements 32 are provided, as visible more precisely in FIG. 6.
- These fixing elements 32 are here collars coming to grip the tube 22 of the crosspiece 20 over its entire periphery.
- the fixing support 30 further comprises two elements 34 for fixing to the structural element 10.
- These fixing elements are here in the form of L-shaped lugs applied against the flat surfaces 161, 162 of the structural element 10 to be fixed with screws 35 (fig. 6). Note that a single fixing point could possibly be envisaged depending on the shape of the structural element.
- the fixing support 30 is fixed under the first passage 14 so as to be fixed to the cross-member 20 at the level of a lower face of the latter.
- the fixing support 30 can then comprise a receiving part 36 of the cross-member which can support the latter but also guide it during its introduction into the first passage 14.
- This fixing is for example carried out by means of a screw-nut system passing through an orifice of the fixing support 30.
- the assembly is thus fixed to the body according to four fixing zones linked to the flanges 23 and 24, at the rear of the fixing support 30, by fixings 37, and at the bottom of the structure.
- the complete mounting method is similar in principle to that of a state-of-the-art dashboard.
- the steering column fixing support 30 is firstly assembled with the incomplete structural element 10 inside the second passage 16. For this purpose, the lugs 34 are pressed against the surfaces 161, 162 of the structural element 10 then fixed by means of screws 35. The fixing support 30 is then positioned as shown in FIG. 2, under the first passage 14.
- the cross member 20 is then introduced inside the first passage 14 through the end 15b thereof.
- the flange 23 is not yet fixed to the end 22a of the tube 22 which is introduced first inside the structural element 10.
- the fastening elements 221-224 of the cross member being fixed to the cross member so as to be disposed between the second passage and the end 15b of the structural element, they do not hinder the passage of the cross member at the level of the fixing support 30 of the steering column.
- the cross-member is inserted by sliding to a position in which the fastening elements 221-224 of the cross-member 20 are in contact with the fastening elements corresponding 141 -144 of the structural element.
- part of the tube 22 rests on the receiving part 36 of the steering column fixing support 30 (FIG. 3).
- the first passage 14 has larger internal dimensions than the cross section.
- the cross member 20 is then fixed to the steering column fixing support 30 by means of the fixing elements 32, and fixed to the structural element 10 by means of the fixing elements 221-224.
- the flange 23 can then be mounted at the end 22a of the cross member 20, either permanently, for example by welding, or removably, for example by means of the screw nut assembly 25a, 25b (FIG. 4).
- a lower part 13 of the structure 10 (fig. 1) is fixed to the lower part of the body called the central floor (not shown). This connection to the floor is made up of one fixing or several screw-nut type fixing.
- the method of mounting the dashboard according to the invention is thus simple and rapid because of the number of reduced parts. It is in particular possible to produce a structural element weighing approximately 13 kg against more than 23 kg for a conventional dashboard body formed from several assembled parts.
